Weichai LOVOL CVT technology leads the innovation and upgrading of domestic agricultural machinery equipment

　　April 23, in China's earliest to meet the sun's reclamation area - Heilongjiang Jiansanjiang reclamation area, the attention of China's first commercial 240 hp CVT intelligent tractor - LOVOL P7000 tractor held a delivery ceremony, domestic large horsepower CVT tractor began to drive into the "black land" in batches, protecting the granary of the country.

　　On October 26, 2021, LOVOL 7000 high-horsepower CVT intelligent tractor was unveiled at the National Conference in Qingdao

　　With the fierce competition situation and the rise of the concept of intelligent agricultural machinery in the past two years, the domestic tractor field has accelerated the pace of upgrading. To know, with the current mechanical transmission technology widely used in the field of domestic tractors, it is almost impossible to achieve assisted driving or even fully automatic driving in the future. Fortunately, with a number of domestic leading enterprises in THE CVT technology force, especially Weichai LOVOL last October detonated the concept of domestic CVT tractors, China's tractor technology upgrading process finally opened a new page.

　　Key technological breakthroughs were made in domestic agricultural machinery

　　CVT technology, which has been common in automobile field and foreign agricultural machinery field, is a new thing in China's agricultural machinery industry. Firstly, agricultural machinery involves complex operation environment, which requires both walking and load operation, making application more complex. CVT technology is difficult to be implemented, and there is a lack of mature industrial chain for support in China. Secondly, due to the higher cost of this technology, in the face of agricultural machinery consumers with weak consumption power, both enterprises and users themselves, the market acceptance was not high in the past few years, so the development and application of this advanced technology in the domestic agricultural machinery field hesitated. Moreover, from the perspective of international experience, the power shift technology lower than this technology is also not mature enough in the application field of domestic tractors in China. At present, the widely used mechanical transmission technology is still lower than power shift.

　　It can be said that if the domestic tractor enterprises have fully mastered the tractor CVT technology, China's tractor product field is equal to the realization of technological iteration jump upgrade, its significance is extraordinary. For a long time, due to the difficulty of this technology and the uncertainty of enterprise operation, few domestic enterprises are willing to take the risk of technological innovation attempt in this area. This blank point, until the end of 2020, the domestic machinery manufacturing "giant" enterprise Weichai Group completed the strategic restructuring and joint innovation of the agricultural machinery leading enterprise LOVOL Heavy Industry, a real sense of substantive breakthrough.

　　Back to October 26, 2021 -- During the China International Agricultural Machinery Exhibition held in Qingdao, China's first commercial CVT intelligent tractor, LOVOL P7000, developed by Weichai LOVOL, was launched with a great impact, becoming an "ice-breaking" move for domestic tractors to break through the bottleneck of high-end technology. The tractor USES the Weichai independent research and development of CVT CVT powertrain, pooling the convergence of segment pairs of planets more efficient transmission technology, a submerged pump motor hydraulic transmission unit high efficiency transmission technology, realize the assignments section of the stepless speed regulation, customized powertrain control strategy for specific conditions, optional field model, transportation, cruise control can be realized at the same time; Realizing the combination of the best power performance and the best fuel economy, the comprehensive operating efficiency can be increased by 30%, the comprehensive fuel consumption can be reduced by 10%, product technology and performance indicators to reach the domestic leading and international advanced level, representing China's agricultural machinery technology and industrial upgrading into a new height.

　　Breakthrough agricultural machinery "bottleneck" technology

　　LOVOL P7000 high-horsepower CVT intelligent tractor solves the "bottleneck" problem of China's high-horsepower intelligent tractor in power system, continuously variable transmission system, hydraulic intelligent control system and other core technologies, and realizes the independent control of core technologies and core components. It has become the first tractor continuously variable power transmission assembly with independent intellectual property rights in China. Chen Zhi, president of China Agricultural Machinery Industry Association, once served as the president of China Agricultural Machinery Institute, said that the appearance of Weichai LOVOL P7000CVT intelligent tractor has far-reaching significance and is the real "light of domestic goods".

　　For a long time, foreign monopolies on the technology and core parts of high-horsepower CVT tractors have not changed. CVT technology threshold is high, there is no domestic experience to follow; In addition, CVT is a system engineering. Both product verification means and manufacturing industry chain in China are relatively backward, which is not enough to support the industrialization of advanced technology.

　　On January 6, 2021, Weichai Group announced the completion of the strategic restructuring of LOVOL Heavy Industry, which became a major event in the domestic agricultural machinery industry. In view of the "strength position" of the two sides, it also kindled the hope of the domestic agricultural machinery industry to break through the western technology monopoly.

　　In the field of large and medium horsepower tractors, Weichai is currently the only enterprise with large horsepower CVT powertrain technology in China. As early as 2012, Weichai went down a step "chess" and Julio cruz, strategic restructuring a proud German Kay group and its linde hydraulics, one hundred brand linde hydraulics of high-end hydraulic technology is introduced into China, innovative building "Weichai engine + linde hydraulics" world's first hydraulic power assembly, high-end upgrade help China engineering machinery, agricultural machinery, Solve the "throat lock pain" in China's industry.

　　In 2018, Weichai, relying on its full range of agricultural power, gearbox and bridge technology advantages, deeply integrated with Linde hydraulic technology, officially began to overcome the CVT powertrain technology. At the same time, through the strategic restructuring of Austria RADIUS Company, collaborative open innovation, a breakthrough in the CORE technology of CVT powertrain.

　　Weichai take advantage of its powerful resources, establishing innovation center in Europe, rally team wisdom at home and abroad, based on the present situation of Chinese agricultural equipment industry chain, based on the existing engine, hydraulic unit, make the most efficient, the most suitable technical route, advanced CVT powertrain performance can be ensured and localization to the ground. Weichai has nearly 100 engineers in hydraulic, electric control, powertrain and other related fields. They have successfully conquered CVT powertrain technology after 3 years of unremitting efforts.

　　At this point, Weichai for weichai Lei Wo product technology continued to upgrade to create the possibility. In the following year, Weichai gold power chain advantages and Weichai LOVOL's previous advantages in intelligent manufacturing of agricultural machinery  were successfully grafted, making LOVOL P7000 high-horsepower CVT intelligent tractor the first to break the benchmark of international technology monopoly.

　　LOVOL unmanned cooperative harvesting operation

　　On November 29, 2021, the Ministry of Agriculture and Rural Affairs and the Ministry of Industry and Information Technology jointly held a meeting in Beijing to promote the work of strengthening the shortcomings of agricultural machinery and equipment. It was pointed out that China's agricultural mechanization and agricultural machinery equipment still have some weaknesses that need to be solved urgently, such as high-end intelligent agricultural machinery and other machinery and equipment gap is large, and high-horsepower machinery is not strong enough. So we need to strengthen agricultural machinery and equipment advanced short board sense of responsibility, sense of mission and sense of urgency and focus on the core technology, key products and key requirements, key link, to breakthrough technology bottlenecks, strive to express the "gap", solve the "chain", break through "their", promote the development of agricultural machinery equipment industry with high quality.

　　The launch of LOVOL P7000 high-horsepower CVT intelligent tractor can be said that Weichai LOVOL, as a leading enterprise in agricultural machinery in China, has made an "excellent answer" of its own in terms of strengthening weak points and strength of agricultural machinery.

　　Solve the dilemma of agricultural machinery transformation and upgrading in China

　　LOVOL P7000 high-horsepower CVT intelligent tractor leads domestic tractors into the era of infinitely variable speed, which has important strategic significance for improving China's agricultural machinery and equipment technological innovation ability and international competitiveness of products, promoting the transformation and upgrading of agricultural machinery and equipment industry to high-tech content, and accelerating agricultural production to achieve high-quality development.

　　For a long time, the application of technology in China's tractor field is still in the era of mechanical shift technology. And foreign countries have long gone through the power shift and into the CVT automatic shift technology stage.

　　In recent years, the domestic leading enterprise of agricultural machinery has been to push power shift and some even through mergers and acquisitions of foreign enterprises have a certain technology, but as a result of these foreign technology is others out, either has the collapse of enterprises, there is no core key technology, real leading core technology is not to sell to us.

　　With the advancement of a new round of technological revolution and industrial change, China's agricultural machinery is accelerating to intelligent high-end upgrade, but if some key technologies have not made a breakthrough, to high-end upgrade is an empty talk. For example, the tractor automatic shift, the liberation of the operator's feet, if there is no solution to the power shift or CVT, it is difficult to achieve automatic navigation assisted driving and the future of full automatic driving.

　　At present, there are three obstacles in the intellectualization of agricultural machinery in China, such as technology, cost and infrastructure, and the first one is technology itself. If the tractor power shift technology or CVT technology is not up to standard, it can not achieve automatic driving. CVT automatic transmission can achieve full automation of shift, providing the possibility for intelligent development and unmanned driving of large tractors, and has been widely used in large tractors abroad.

　　Weichai's strategic reorganization of LOVOL Heavy Industry is the reorganization and reconstruction of the world's largest engine enterprise to China's largest agricultural equipment enterprise. Good technology costs money, and it takes time. Weichai Group, which focuses on core technological innovation, and LOVOL Heavy Industry have more than 20 years of technological accumulation in the field of agricultural machinery, and can take the lead in the development of CVT tractor, which seems to be taken for granted.

　　It is reported that Weichai LOVOL invested 2 billion yuan in the construction of high-horsepower intelligent tractor factory has been started in 2021, after completion will have a comprehensive annual capacity of 100,000 units of tractors, will fully fill the domestic CVT tractor, high-horsepower intelligent tractor field market gap, accelerate the domestic cutting-edge agricultural machinery technology level with the international first-class. In addition to bringing more intelligent and comfortable product experience to domestic users, it also drives the domestic agricultural machinery industry to accelerate the transformation and upgrading and enter the track of global agricultural machinery competition as soon as possible.

　　Seize the global agricultural machinery high-end value chain

　　On the morning of November 3, 2021, the National Science and Technology Award Conference was held in the Great Hall of the People in Beijing. Weichai LOVOL participated in the project of "Key Technology and Application of Agricultural Machinery Automatic Navigation Based on Beidou", which won the second prize of National Science and Technology Progress Award, which is the only National Science and Technology Progress Award in agricultural machinery field of the year. CVT tractors equipped with Beidou navigation enable farmers in the new era to "push button" operation, which means that agricultural production is constantly stepping into an intelligent era.

　　In 2022, Weichai LOVOL's global innovation "grand chess game" has won more victories. It has set up science and technology innovation centers in North America, Europe and Japan, further relying on Weichai Group's advantages in global core resources and technological innovation to attract high-end professionals. By focusing on cutting-edge technology, attracting global talents, allocating global resources and conquering key and core technologies to achieve efficient coordination, Weichai LOVOL will comprehensively improve its agricultural equipment R&D capability.

　　For a long time, influenced by various factors such as national conditions and historical development stages, Chinese agricultural machinery enterprises have been wandering in the middle and low end of the global agricultural machinery industry value chain. With the continuous improvement of China's national strength, it is inevitable to seize the high-end market of international agricultural machinery supply chain and value chain. From the current situation, in 2021, the sales revenue of international agricultural machinery giant John Deere is about 170 billion yuan, while the size of domestic agricultural machinery enterprises is far from that of international giants, which also shows that there is a long way to go.

　　The journey is strong. With Weichai LOVOL's amazing leap in the field of CVT technology and the unremitting efforts of more and more domestic agricultural machinery enterprises, it means that China's agricultural machinery has more and more courageous "core base" in the process of catching up with the advanced level of international agricultural machinery and seizing the high-end value chain of global agricultural machinery.
